The effect of electrolytes in the temperature profile of saline extractive distillation columns is analyzed using a Newton–Raphson based program (acronym GKTM) with a new increase-bystep technique and applied to the system 1-propanolwater-LiNO3. In addition, the E-NRTL model is examined in order to validate its capability of making accurate predictions of phase equilibrium behavior and its suitability for simulation of extractive distillation columns. Special aspects of the phase equilibrium of mixed solvents electrolyte systems are analyzed. These particular features determine the special temperature profile in these cases.

AbstractA phase equilibrium study of the system aluminiumbromide and pyridiniumbromide has been carried out. The phase diagram of the system indicates the existence of three congruently melting com pounds of the molar ratio AlBr3/PyHBr 1:1, 1:3, 2 :3 and one incongruently melting compound of the molar ratio 1:2 and is therefore similar to the AlCl3-PyHCl system [1].

Abstract The partitioning of atmospheric hydrocarbons into vapor and condensed phases when the species count is large is considered using the formalism of continuous thermodynamics. The vapor saturation pressures and condensate species distribution are parameterized using the species normal boiling temperatures. Qualitative trends in activity coefficient values and phase equilibrium behavior that are relevant to the outer planets and Titan are discussed in terms of a much simplified perspective on these aspects of partitioning. The trends found are generally consistent with those from other published atmospheric model results.
